' sra'rss HENRY PI'IMAN, Ol? ELIZABETH, NEW JERSEY, ASSIGNOR TO UNDERVVOOD COM- PUTNG MACHENE COMPANY, OF NEW YORK, N. Y., A. CORPORATION OF NEVI Y YORK.

Z o all -w /wm it may concern Be it known that I, HENRY L. PITMAN, a. citizen of the United States, residin in Elizabeth, in the county of Union and i tate of New Jersey, have invented certain new and useful Improvements in Combined 'lfypewriting andY Computing Machines, of which the following is a specification.

This invention relates to computing machines, and is herein disclosed as applied te a combined typewriting and eomputing machine of the Underwood-Hanson type`l wherein the numbers written by the numeral keys oi the typewriter, while being written are setup by means ci pins on pin-bars, and after numberis completely set up in this way, it is carried into the computing `\vheels.

ln such machines, the mechanism is somewhat complex, and the movements oi" parts, especially' in the operationV of setting up numbers, are necessarily small but eX- tremelyaccurate, with the resnlt that the 1 machine issomewhat diflicult to assemble.

Moreoven adjustments may become deranged it dirt is allowed to accumulate in the hearings or between bearingpoints.

yThe pre t invention is more especially directed te Lhestructureknown as the transpvcsition device, by means of which numbers, which are written on the work-sheet on the platen, which travels to the left, may be set 'up en the proper pinbars beginning at the left and going toward the rights This transpositi Ldevice, in some forms ot the mechanism already in use, comprises arms which are adapted to thrust forwardly to a small extent the pin-bars, so that the pins thereon, which are normally out o' alinement with the pinsetting bars, may be brought into alinement with said bars, with the resuit that anyactuated bar sets up a pin on the bar 'which has its pins in `alinenfient at the moment. i

According to the present invention, the jacks which are usually adjacent the tyijic writer'. carriage, and selectable by a og thereon may he caused to eiect the selec Specication of Letters Patent.V

tion by displacing the usual rods, and each rod may be directly connected to move its own pin-bar by a one-piece bell-crank, or bail in the form of a bell-crank, thus reducing the number oi bearings. i In other words, many parts are eliminated and all the work is done by mechanism of simpler construction. it has been the practice to connect the lower ends of these rods to the horizontal arms of bell-cranks, and then to connect the pendentarms of said bell-cranks to a complex transposition device. According to the present invention, however, there may be 1 used for connecting said rods to the pinbars (or computation-bars) no more than a single set of bell-cranks, and these may not only change the up-and-down motions of the rods to the backend-forth,motions Y of the pin-bars, butmay also constitute a transposition device, since one set of bell crank-arms has the reverse denominational order from the other set of bell-Cranknrms To eii'ect this reversal, the bell-cranks are mainly made in the form of graduated hails, and the bails are so formed and nested as to give the desired result. One of the main features of the invention therefore is the provision of bell-cranks 'forming in themselves a transposition device between the rods and the pin-bars. i

rEhe set or system of computation-bars is usually of substantially greater width than the set oi' rods or denominational devices, the latter being usually arranged at letter-` snace intervals;` and one oi' the :features of the invention is that the bail-like bellcranks'are so contrived that one set of arms, for connection to the rods, is of substantially less width than the other set of arms, 'for connection with the computation-bars. Thus there are three advantages gained, first, the connection of the rods to the coinputation-bars by a simple set o i: bell-cranks; second, the bell-cranks constituting in themselves a transposition device, and, third, the bell-cranks compensating for the difierence in width between the set of rods and the set of ciomputaftionbarsF AV fourth ad vantage is gained in that the bell-cranks are simply and readily mounted upon a support in a manner to be assembled as a unit for attachment to and detarhment from the machine. Since these hails or bell-cranks may all be ournaled on a common shaft and held in place by a comb, the mechanism is easily assembled and may be readily made ont oi stamped metal parts, thus rendering it possible to build a strong and yet inexpensive device.

Other features and advantages will here inafter appear.

In the accompanying drawings,

Figure l is a Sectional side vie-.v oi an Underwood-Hanson bookkeeping' machine, showing the present invention as applied thereto.

Fig. 2 is a perspective view et the transposition device detached l'rom most of the machine.

Fig. 3 is a perspective view ot a bail or bell-crank forming1 part of the transposition device.

Fig. fl is a sectional Front view ot the bellcranks or hails.

In the usual Underwood-Hansen bookkeeping machine. the numeral keys l and alphabet keys 2, when depressed, carry dov-:n their key-levers se as to rock bell-cranks to carry type-bars 5 upwardly and rearwardly against the platen 6, so that types thereon vxill print against the tren*YY et the platen.H The typewriter c travels on front and rear rails and is drawn along by a springl herr shown.

In order to control the travel ot the carriage. there is provided the usual ack bar 10 meshing` with a pinion 1l connected. to the escapement vfheel ft2. said Wheel oe-...ig adapted to he engaged alternately hy the dogs 18 in the nsnal manner when the nniversal har 'ill is struck by the usnal heels l5 on the type-bars. Whenever numeral hey is depressed, it carries down its pendant l? to strike a rock arm on a rock L). to ectnate if.' etti-nq linkage 20 to .vhich the rock shart is connecten. One form ot mechanism showvingr this and some other features is shown in the application et Frederick A. Hart. Serial No.. 783.258. 'tiled rinag'nst G, iJlB (new Patent 'flo, 1,287; 301i., dated December l0, 1.918). The pinsctting linkages 2O are adapted to set up on pin-hars 2l pins 22 in an order determined bj; the vriter carriage. the pins set up depending on the numeral key l, which is actuated at any moment. Normally the pins 22 are in the position shown in Fig. Where they are seen out ot alinement with their linkages 20. In the addingzone, however. the pin-bars 2l are moved forward "fztm to bring' their pins into setting position. To effect this, there is provided Ythe usual denomination-Selector 23 adjustably mounted on the typewriter carriage, and adapted to be carried along' thereby under the front ends of jacks 2er. so as to depress the rear ends of said jacks and carry down the rods or vvires 25, there being` one rod for each jack. Between the wires or rods 253 and the pin-setting' bars 2l, the connections form part of a transposition device which includes a series oiu bell-crank arms 2G, each having a hook 27 into which the lower end of its Wire 25 is adapted to be inserted and to rest. so that when the Wire 25 is depressed, the arm 26 will he depressed and rock forwardly the depending arm fast to the arm 26. said arm 28 having' a hook 29 which may he like the hook 27. and which is adapted to lie against the pin 2O at the rear end oi its pin-bar 2l. The bell-crank arms 2G and 23 are connected by bail members 3l inteleral therewith, so 'that the two arms 26 and form a bell-cranl, as seen in 3. The arms 26 are journaled upon a shat 1` 2,\vhich is in turn mounted or journaled on upright arms and 34 forming.' a mounting' for the shaft. In order to held the si tt 32 in place. one enc. may enter socket in the arm 34, and. the other end may rest intlie open fork at the unser end ot the arm 39 and be held therein by spring); latch di adanted to a re(J ed portion 3S et the shaft.

In order to hold the arms 2S properlyY spaced. so that thev lie adjacent their ovvia nin-hars 2l, the nl ehs and 34 p rt i7 comb in the torri et a U-shapod 'i metal having its bent-over ears 40 held y screws to the uprights and 34.

In order to le be done in a specially hulls m is provided on the comb an ad' 46 held thereto by screws L15.7 and may be .ingr other e han* LIB are with adjustable screws 48, against which the 1 screwed by the screws 52 passing through openings 53 at the lower end of the plate 50. These rods extend rearwardly from a plate 54 which is curved to iit them, and to which they are held by screws 55,-the plate 54 bcing fast to the usual bracket 56.

As will clearly be seen from Fig. 2, the arms 26 and 28, together with their bail parts 3l, form two overlapping nests of bails standing clear of each other, the two sets of bailsv being substantially at right angles to each other. Owing to the fact that the bails 31 are of considerable length, the openingsl 42 in them give them a good bearing on the shaft 32. @ne of the arms 26,namely,theV center one, forms with its dependent arm 28 a bell-crank without any intervening bailfand to give this arm the desired bearing, it may have a hub 57 by which it is journaled on the shaft 32. As will be seen from Fig. 2, half the bails,y 31 are above the hub 57 and the other half are in front of said hub.

When any jack is raised by the selector 23 to press its rack bar 2l forward, it does so against the tension of a spring 58 which normally draws yaV detent arm 59, made of doubled over sheet metal and having a roller .60 between them, lagainst an elbow 61 of the pin-bar 2l. Thus, the spring 58 holds the pin-bar in its rearward position. The def tent arm 59 may comprise an opening 60a, thus enabling each of its metal sides to have a point 61a seatedin a hollow or opening 62 of' a cross-bar 63, so that the detent arm turns freely on its point. In order to keep the detent arms properly spaced from each other, the bar 63 is provided with spaced collars 65. This bar .63 is conveniently formed from a solid shaft having the spaces between the collars 65 turned down to form grooves into which extend detent arms 59,

and then being channeled lengthwise to ttorm the opening 62.

ln order to compute the numbers'set up on the pin-bars, the operative may draw on ahandle 65 to actuate in the usual way the general operator 67, so that its cross-bar 68 will strike the abutments of the depressed pins, therebyV driving the pin-bars 21 forward so that each turns its computing wheel 68a.V rOri-the return stroke, the usual carry-v over mechanism 69 effects carry-overs, and the pins are restored in the usual manner by the pin-restoring plate 70. rlhe bar G8 may be supported on arms 7l fast to the upper part of a comb 72, said comb in turn being fast to the top of a bottom comb 73 which is held by screws 74: on the front ends of the rods 51, there being an opening between the combs 72 and 73. f

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
